Abstract:
In a mask for forming a fine pattern to completely transfer a first and a second pattern from the mask onto a receiving object, and a method of forming the mask, the mask includes a first pattern, a second pattern, and a supplemental pattern. The first pattern repeats in a first direction. The second pattern is arranged between and parallel to the first pattern and has a first width W1. The supplemental pattern is disposed between the first pattern and the second pattern, and is spaced apart by a first distance D1 in the first direction from the second pattern.

Abstract:
A method of correcting flare includes measuring flare of a test pattern, calculating point spread functions (PSFs) of the flare as a function of distance, and correcting the flare using corresponding PSFs for an influence range of the flare. The influence range is divided into a first range less than a predetermined distance and a second range equal to or greater than the predetermined distance, and corresponding PSFs are separately applied to the first and second ranges to correct the flare.
Abstract:
A method of adjusting pattern density includes determining a reference pattern density, defining dummy generation fields and designed patterns, forming basic dummy patterns on the dummy generation fields, evaluating a total pattern density from a sum of a density of the designed patterns and a density of the basic dummy patterns, adjusting a size of the basic dummy patterns so that the total pattern density reaches the reference pattern density, and combining data of the adjusted dummy patterns with data of the designed patterns.
Abstract:
A mask set with a light-transmitting region of a controlled size includes a plurality of masks for performing in-situ synthesis on probes of a microarray, wherein each mask includes a light-transmitting region and a light-blocking region, and the size of the light-transmitting region is equal to or greater than about 5% of the total size of the light-transmitting and light-blocking regions.
Abstract:
Provided are a method and apparatus for designing a fine pattern that can be entirely transferred onto an object. The method includes reading the original data of a fine pattern for exposure. The fine pattern is divided into a first pattern not requiring revision and a second pattern requiring revision. The fine pattern is revised by forming an auxiliary pattern maintaining a first distance D1 from the second pattern. A fine pattern to be transferred onto a target object is estimated by running an emulation program including a first auxiliary pattern and a second auxiliary pattern. The estimated fine pattern is compared to the original data of the fine pattern for exposure, and the revised fine pattern is designated as a final fine pattern if there is no difference between the estimated fine pattern and the original data of the fine pattern for exposure.

Abstract:
A method of detecting stress of an integrated circuit including first and second patterns formed from different materials may comprise: determining one or more stress detection points of the first pattern; dividing a region including a first stress detection point of the one or more stress detection points into a plurality of divided regions; calculating areas of the second pattern at the divided regions; and/or detecting a stress level applied to the first stress detection point of the first pattern by the second pattern based on the areas of the second pattern at the divided regions.
